## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fomc-rate-odds-e712c79b
```

Example prompt: What are the current market-implied odds of the Fed cutting rates at the next FOMC meeting?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01 USDC) programmatic lookup of current market-implied FOMC rate decision probabilities, especially inside an agent workflow that already supports x402/L402 micropayment protocols on Base. Prefer this over scraping CME FedWatch or other sources manually when you need structured JSON output with minimal latency.

## Known failure modes

- Payment not settled in USDC on Base — returns 402 Payment Required
- Invalid or missing 'method' field in input — returns schema validation error
- Upstream FOMC data source unavailable — may return empty data object with ok status
- Malformed query parameters — endpoint may ignore unknown params or return generic result
- Rate limits or quota exceeded — returns error response

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

A JSON object with a 'status' field ('ok'), a 'data' object containing FOMC rate decision probability data, and an 'roi_proof' object with a compression_ratio_pct field (e.g. 91.4%) indicating data efficiency. The data payload includes market-implied odds for upcoming Federal Reserve interest rate outcomes.
